The Rob Roy cocktail is similar to the beloved Manhattan, except the Rob Roy calls for scotch instead of American whiskey. The swap from bourbon (or rye) to scotch may not seem significant, but the difference is notable. And delicious.

While the Manhattan dates back to around 1880, it’s believed that the Rob Roy first appeared more than a decade later, likely around 1894 at the Waldorf Astoria’s original location on Fifth Avenue. According to Frank Caiafa, NYC bartender and author of “The Waldorf Astoria Bar Book,” the drink was inspired by an operetta named “Rob Roy,” which was performed at the nearby Herald Square Theatre. Created by the composer Reginald De Koven and lyricist Harry B. Smith, the operetta was loosely based on a Scottish folk hero who was a Robin Hood-like figure named Rob Roy MacGregor.

Like any good spirit-forward cocktail, the Rob Roy is an opportunity to highlight what’s in the glass, not hide it. Any number of scotches can yield a great drink, so choose your favorite. But note that you want a bottle that will pair with the herbal, bittersweet vermouth. Blended scotch is the usual choice. Single malts can certainly work, but anything too heavily peated may overpower the vermouth and lead to an unbalanced drink.
